Lastly, Piper gave a progress report on its PiperJet, which has now amassed 130 flights and 200 hours of flight time. Kromer said that based on current aerodynamic data, the airplane was a lock to make its guaranteed speed, range and climb performance guarantees. Becker, who was in charge of the design of the jet, said that a breakthrough had been achieved on the design, thanks to a new passive thrust vectoring system pioneered by Williams International, supplier of the FJ-44 that powers the jet. The system automatically adjusts the thrust vector at low altitude to compensate for the nose-down pitch change that naturally results from the high-mounted engine. Becker said the addition would obviate the need to add active trim compensation. To punctuate the update, the PiperJet made several passes over the flightline at EAA AirVenture shortly after the announcements.
